Update to stringfield handling so that side-effects on
parameters are not evaluated multiple times.

An example where this caused a problem was in chan_sip.c, with
the line

  ast_string_field_set(p, fromdomain, ++fromdomain);

This patch was originally uploaded to issue #13783 by
jamessan. While the issue was closed for other reasons, this
patch is valid and fixes a separate problem, and is thus
being committed.
